Feb 1, 2025

February 2025 monthly summary for SonarSource/orchestrator focusing on feature delivery, stability, and scalability improvements. Delivered a targeted memory optimization to improve performance and stability for larger/complex operations. The Orchestrator Server memory upgrade increased the Java heap (Xmx) from 32m to 128m and was validated through server CLI factory paths and unit tests. This change enhances scalability, reduces risk of GC-related slowdowns, and supports more demanding workflows.

Nov 1, 2024

November 2024 monthly summary for codescan-io/sonarqube: Focused on delivering a multi-product aware version resolution and releases API. Key feature delivered: Product-Type Aware SonarQube Version Resolution and Releases API Enhancement, which updates the SonarQube version dependency in build.gradle, enhances UpdateCenterClient and ActiveVersionEvaluator to correctly determine SonarQube versions based on product type (Community vs Server), and modifies UpgradesAction to include the product type in the releases JSON response. This improves upgrade automation accuracy for multi-product deployments, reduces risk of incorrect version upgrades, and provides clearer product-specific release data for automation.
